How are one and zero values read?
Communications and digital processing depend on the ability to decode and read the one and zero values of logic waveforms. In Fig. 3, the leading edge of the clock waveform initiates the data-signal inspection process. It looks at the data signal to determine whether there are one or zero logic values. Fig. 3. A jitter-free data signal and a clock signal initiate the data-reading process. Inspection, in this example, is undertaken at the center of the data signal. This region of the data waveform is least ambiguously a one or a zero.
